The present invention relates to a card for recording as a reproduced image of a hologram and a method for reading the information.

(Prior Art) Conventionally, in a magnetic card, card-specific information such as a personal identification number is recorded on a magnetic stripe provided on the card surface. The information recorded in this way is often erased and confused by the influence of an external magnetic field, or is easily rewritten and abused by a commonly available magnetic read / write device to improve the security of the information. There was a lack of surface. Therefore, various anti-counterfeiting methods for such a card have been attempted, and one of them has been provided with a hologram having unique information. In this method, illumination light is applied to the hologram provided on the surface of the card, and the spot that appears at any point on the line of the reflected light or transmitted light is read as information, but the hologram is reproduced with a simple light source. Therefore, the information may be easily read, and the amount of recorded information is limited.

(Object of the Invention) The present invention has been made in view of the above points of the present invention, and an object thereof is to provide a card having card unique information that cannot be easily forged and a method for reading the information.

(Summary of the Invention) The present inventors have made it possible to reproduce reproduced images reproduced from a plurality of different portions of a hologram in substantially the same area, not as recorded information as bits of a reproduced image of a hologram. Then, the present invention can be achieved by finding that the recorded information cannot be easily read and rewritten.

That is, in the card of the first invention of the present invention, at least one hologram is provided on the card substrate, the one hologram is divided into at least two or more parts, and each of the divided parts is respectively divided. Different reproduction images are recorded, and the reproduction images reproduced from the respective portions are reproduced substantially overlapping in the same area, and the card information reading method according to the second aspect of the invention is at least 2 At least one hologram is divided into the above parts, different reproduced images are recorded in the respective divided parts, and reproduced images reproduced from the respective parts are overlapped and reproduced in substantially the same area on the substrate. A method for reading information from a card provided in, wherein a reproduced image reproduced from each area by sequentially illuminating the divided portions with reproduction light.

(Example) Hereinafter, the Example of this invention is described based on drawing.

 FIG. 1 is a plan view of the card of the present invention.

The hologram 10, the hologram 20, and the hologram are arranged at the array position according to the card-specific information recorded on the card substrate 1.
30 are provided.

In these holograms, a plurality of reproduced images are recorded separately in different parts, and each reproduced image is reproduced by illuminating each part with reproducing light, but when the entire surface of the hologram is illuminated, a plurality of reproduced images are generated. It is impossible to recognize individual reproduced images by reproducing at the same time.Each reproduced image contains pattern information that is a combination of the shape, number, and arrangement position of the images that the card-specific information forms the reproduced image. It is recorded.

As a method of creating such a hologram, a transparent original for creating a hologram having a pattern of an image of card-specific information to be recorded is prepared, and an object light obtained by irradiating the transparent original with a laser light or the like is preliminarily set at a predetermined portion. The information is recorded by a method in which a hologram is recorded on a photosensitive material for hologram recording which is masked to form a hologram in a part, and this operation is sequentially repeated a necessary number of times to create a plurality of partially different holograms. There is a method in which a plurality of recorded relief holograms are created, these are joined together to form a mold for duplication as one relief hologram, and a hologram is created using this.

As the above-mentioned hologram, conventionally known holograms can be widely used, but in particular, laser reproduction holograms such as Funnel hologram, Fraunhofer hologram, and lensless Fourier transform hologram are suitable.
Further, a hologram in which a rainbow hologram for the purpose of decoration is multiplex-recorded can also be used in the above hologram, and in this case, a reproduced image of the rainbow hologram can be obtained by its own color light.

Functionally, either a reflection hologram having a light reflecting metal thin film layer or a transparent hologram having a hologram effect layer can be used. When a transparent hologram is used, it is provided on a card substrate. It has the advantage that a hologram can be provided on the image and more advanced information can be added by combining the image information of the card and the reproduction information of the hologram, and it is excellent in terms of design appearance without disturbing the design of the card. Becomes

As a method of providing such a hologram on the card substrate, a duplication mold obtained by forming a relief hologram by a known method is used to directly heat the material for forming the hologram provided on the card substrate by heating.

Next, the information recording / reproducing method of the card of the present invention will be described.

3 (A) and (B) are explanatory views showing an example of the information recording method of the present invention.

Reference numerals 100, 200, and 300 in FIG. 3 (A) respectively denote portions on the card substrate 1 on which a reproduced image of the hologram 10 is recorded, and the portion 100 has reproduced images 1001, 1002, and 1003.
However, reproduced images 2001 and 2002 are recorded in the portion 200, and reproduced images 3001, 3002, 3003 and 3004 are recorded in the portion 300.

As shown in FIG. 3 (B), these reconstructed images are composed of an image that is a collection of squares, and information such as the reconstructed image 1001, 1002 and 1003 have PIN code,
Reproduced images 2001 and 2002 show the name of the card owner.
These 3001, 3002, 3003, and 3004 check digits are recorded as follows. Although not shown here, information is recorded on the hologram 20 and the hologram 30 by the same method as the hologram 10.

Such a hologram is formed on the card at an array position corresponding to the card-specific information, and information recorded by the reproduced image and information recorded by the positional relationship of each reproduced image with respect to the card (for example, in the present embodiment, The hologram 10, the hologram 20, and the hologram 30 are provided from the right end of the card, and this array means a specific card issuing place. ] The card-specific information is recorded on the card.

In the present invention, since information is recorded as described above, the number of holograms provided on the card may be one or more, the formation position is not limited, and the reproduced image thereof is formed. The shape, number and arrangement position of the images are not limited, and for example, if the pattern of the reproduced image is recorded as a bar code, it can be handled as bar code information such as JAN code and NW-7 code.

As described above, the hologram is formed on the surface of the card to record the unique information on the card. However, since the recorded unique information does not show a reproduced image of the hologram in white light,
The card only looks like one provided with a thin metal or plastic film.

However, if the portion of the hologram formed on the surface of the card substrate on which one reproduced image is recorded is proved by laser parallel light or the like, the hologram forms the reproduced image and the light receiving portion provided at the reproducing position. A reproduction image equivalent to that of the transparent original is projected on the card, the card-specific information can be read, and the authenticity of the card can be determined. However, when the entire surface of the hologram is illuminated, a plurality of reproduced images are reproduced at the same time, so that individual reproduced images cannot be recognized and information cannot be read.

FIG. 4 is an explanatory view schematically showing a method of reading information when a laser is used as a light source for hologram reproduction.

A portion 10 in which reproduced images 1001, 1002, and 1003 of the hologram 10 on the card in which the laser beam oscillated from the light source 60 is magnified to a required size by the magnifying optical system are recorded.
0 When illuminated, the hologram forms an image, and the light-receiving section is provided at the position of the reproduction distance that depends on the conditions when the hologram was taken.
The reproduced images 1001, 1002, 1003 are projected on 70, and the information recorded by the pattern of the combination of the square shape, the number, and the arrangement position forming these reproduced images and the position information of the reproduced image with respect to the card are read. . Next, sequentially shift the card to illuminate only part 200 and part 300 and hologram
Read the information recorded in 10, then hologram 20,
By performing the same operation (not shown) on the hologram 30 and reading the information recorded on each, the card-specific information recorded on the card can be read and the authenticity of the card can be determined.

The light source 60 used for the above reading may be one capable of reproducing a hologram, for example, a discharge lamp such as a mercury lamp, a sodium lamp, and a metal halide lamp having a narrow emission wavelength, a gas laser, a semiconductor laser, or the like. Further, lasers, EL panels, light emitting diodes, etc. can also be used.

As the light receiving unit 70, a photoelectric tube, a photomultiplier tube, an image tube, an SEC tube, a SIT tube, an image pickup tube such as a vidicon or a saticon, an MO
Solid-state image pickup tubes such as S-type, CID-type, CCD-type, BBD-type, and PCD-type can be used, but it is particularly preferable to use a CCD image sensor, a photodiode array, a phototransistor array, or the like configured of these.

(Effect of the Invention) In the present invention, the hologram of each divided portion reproduces a reproduced image corresponding to the information of the card in substantially the same area, so that the recorded information is the same as the light source at the time of recording. It is difficult to read each divided portion from the same angle as the incident angle of the reference light at the time of recording by using the light source of No. 1, and the entire surface of the hologram is illuminated with the reproduction light. Also, it has a very high anti-counterfeit property that individual reproduced images overlap and the information cannot be read.
